Click defense: green danger

Save a distant planet from getting invaded by funny-looking aliens! In this shooter, you will have to send those evil creatures back into space where they belong! But these guys just keep getting tougher... Use the experience earned from each level for upgrades on various skills, so that the slimy scum that is invading the planet realizes that you are not a force to be reckoned with. Good luck!
